Lychee trees prevent and cure felt in winter and do more with less

Litchi felt disease is caused by litchi. In the young shoots and young ears of litchi, the leaves and flower ears are damaged, the leaves are twisted, the flower buds are swollen and deformed, and they are covered with felt. The lychee is hidden in the felt. If the spray is controlled, it is difficult to kill the litchi. Oh, it is impossible to cure litchi felt disease. If the Qingyuan is combined in the winter, the damaged branches and leaves are cut off, burned intensively, and then sprayed and controlled, the lychee can be completely killed, and the occurrence and harm of the second year can be obviously alleviated, which can do more with less. The specific prevention methods are as follows:

After the winter lychee autumn shoots are fully turned green and mature, the clearing garden is carried out, and the weeds and litter falling fruits in the orchard are first cleaned, and the inner branches of the canopy and the weak branches and dry branches outside the canopy are Cut through dense branches, overlapping branches, and pests and diseases, especially pay attention to cutting off the branches and leaves with felt disease, and then concentrate on the outside of the garden to bury or burn. Finally, spray a 0.8~1.2 Baume aqueous solution of sulphur solution inside or outside the crown, or 15~20 times of aqueous solution of pineine mixture, or 300~400 times of 45% sulphur mixture crystal solution, or 500~600 times 29% sulphur sulphur The aqueous solution of the aqueous solution uniformly sprays all the branches and leaves inside and outside the crown. In this way, the wintering lychee on the branches and leaves can be significantly reduced, so that the young leaves and flowering ears that are picked up in the second year are less affected by the lychee, and there is no felt disease.
